NOTE: Do not expect this tool to be a perfect solution for running Windows from USB. Firstly, USB thumbdrives are typically slow (although you can get faster hardware at a higher cost) and on top of that, Windows Vista / 7 / 2008 do not have built-in USB 3.0 support and so this will only work from a USB 2.0 port with those operating systems.

On top of that, drivers and activation issues are likely to occur on different machines.
